TV Bites: Betty White Books a Mother's Day Date

· It's taken months of tireless Facebook campaigning, but fans now have official confirmation of Betty White's upcoming Saturday Night Live episode in the form of a date: May 8. Although the former Golden Girl does not actually have children, Lorne Michaels validated her Mother's Day booking by explaining, "She's the mother of us all in comedy." Apparently, this mother needs her little helpers, because Michaels has enlisted six former female SNL cast members to join the comedy legend for the episode; Tina Fey, Amy Poehler, Molly Shannon, Maya Rudolph, Ana Gasteyer and Rachel Dratch will all help to lighten White's sketch load at Studio 8H. A band for the May 8 show has yet to be announced. [People]
